React Router Declarative Mode

Declarative mode is React Router's simplest mode using <BrowserRouter>, <Routes>, and <Route> for basic client-side routing without data loading features like loaders or actions.

When to Apply

Using <BrowserRouter> for routing
Configuring routes with <Routes> and <Route>
Navigating with <Link>, <NavLink>, or useNavigate
Reading URL params with useParams
Working with search params using useSearchParams
Accessing location with useLocation

Critical Patterns

These are the most important patterns to follow. Load the relevant reference for full details.

Basic Route Setup

Configure routes with JSX using <Routes> and <Route>:

import { BrowserRouter, Routes, Route } from "react-router";

function App() {
  return (
    <BrowserRouter>
      <Routes>
        <Route path="/" element={<Home />} />
        <Route path="about" element={<About />} />
        <Route path="dashboard" element={<Dashboard />}>
          <Route index element={<DashboardHome />} />
          <Route path="settings" element={<Settings />} />
        </Route>
        <Route path="users/:userId" element={<User />} />
      </Routes>
    </BrowserRouter>
  );
}

NavLink Active States

Use NavLink for navigation with active styling:

import { NavLink } from "react-router";

function Nav() {
  return (
    <nav>
      <NavLink
        to="/"
        end
        className={({ isActive }) => (isActive ? "active" : "")}
      >
        Home
      </NavLink>
      <NavLink
        to="/dashboard"
        className={({ isActive }) => (isActive ? "active" : "")}
      >
        Dashboard
      </NavLink>
    </nav>
  );
}

Reading URL Params

Use useParams to read dynamic route segments:

import { useParams } from "react-router";

function User() {
  const { userId } = useParams();
  return <h1>User {userId}</h1>;
}

Working with Search Params

Use useSearchParams for query string values:

import { useSearchParams } from "react-router";

function SearchResults() {
  const [searchParams, setSearchParams] = useSearchParams();
  const query = searchParams.get("q");

  return (
    <div>
      <input
        value={query || ""}
        onChange={(e) => setSearchParams({ q: e.target.value })}
      />
      <p>Results for: {query}</p>
    </div>
  );
}
